Estimation of peak dosage of kinetic acoustic measures from pressure measurements as derived from time-limited signal waveforms

Year: 2024

Type: article

Abstract: This study builds on Dahl, Bonnel, and Dall'Osto [J. Acoust. Soc. Am. 155(5), 3291-3301 (2024)] by empirically demonstrating the equivalence between peak kinematic values (acoustic displacement, velocity, acceleration) and peak dynamic values (pressure). Methods for estimating peak levels from pressure are developed and tested on signals from impulsive sources used in the Seabed Characterization Experiment (2022) and a towed narrow band sonar source from the Target and Reverberation Experiment (2013). The comparison between peak kinematic levels and peak pressure falls within the calibration uncertainty of the vector sensor. The analysis shows that, for typical monitoring scenarios, peak pressure measurements are sufficient to monitor peak kinematic dosages.
